Emergency-operations-center staff want the cluster to refuse new virtual machines if leftover capacity would not cover a restart after one host fails. Which vSphere feature is that reservation?
Select an answer to reveal the explanation.
Short Explanation
Admission control is the EOC keeping an empty bunk for the night shift. If filling a new VM would steal that bunk, vSphere says no. Edge HA protects NSX services, and FT is a live twin, not a cluster-wide spare-capacity lock.
Full Explanation
vSphere HA admission control reserves cluster CPU and memory so remaining hosts can restart virtual machines after a defined host failure. That is a vSphere cluster feature, not NSX Edge active/standby failover of centralized services. Fault Tolerance maintains a live secondary for selected VMs and is not the cluster admission mechanism. Load-balancer health monitors test application backends, not host-failover capacity.
